This paper presents the theoretical study and experimental verification regarding an improved design for accomplishing the complete rotating balance of assembled type conjugate disk cams. In particular, a pair of assembled conjugate cams consisting of two arc-slotted disk cams and an axially outward counterweight bump integrally formed on each cam is conceptually designed for simultaneously satisfying the conditions of static and dynamic balance. In order to find the feasible solutions of the counterweight bumps, a theoretical approach is developed, and an optimization model is established for searching the optimal solution. Subsequently, two hardware prototypes of conjugate cam mechanisms with a pair of original or counterweighted conjugate cams were designed and constructed, and experiments were conducted for measuring and comparing their yielded shaking forces and vibrations. Experimental results showed that with the use of counterweighted conjugate cams, the yielded shaking forces could be lowered, some of the yielded vibrations could be restrained, and most importantly, the intensity of resonance phenomena could be decreased. Therefore, the presented improved design is feasible and effective for enhancing the dynamic performance of conjugate cam mechanisms.
